PACKAGE AND CLOSURE MEANS. Application filed February 27, 1924. Serial No. 695,393; v

This invention relates to a package and tained to insert an instrument for removing closure means for the same as well as a the side seal cap from said container. novel form of container. Another object of the present invention is The general art of seals for containers, for a sealed package. comprising a container the purpose of understanding this invention, with a closure. cap seated thereon to form no may be classified into two types, namely, a suitable seal, with the edge of said cap friction seals and hermetic seals. Friction extending outwardly from said container seals to be considered are those in which a and a projection extending from said concap is held in position by the friction of tainer substantially equal to, or slightly 1 some portion ofthe cap on the side wallor greater than the maximum diameter of a 5 under a ledge on the container. Hermetic closure cap and adjacent the lower edge seals referred to are those in which the cap thereof whereby the projection on the conis held in position by means of a gasket tainer protects the said closure cap and prewhich is forcibly seated against the side wall Ven s loosening the seal during shipping or of the container.

I ment whereby-suitable depth may be ob- Referring now to the drawings which ila a container comp ont iner; tion above the head, a sealing zone between stands a considerable the side wall of the container, and this dis- 1 lustrate the preferred form-of the invention, the disclosure cap A is provided wlth a cover portion 1 from which depends a skirt 2, which skirt preferably is provided with concave bead 4that is corrugated in the concave part thereof to form friction sealing members and is provided onl its lower edge with a suitably formed wire edge 5 as is common in the art. As a matter of fact, this closure cap is merely used for illustrative purposes of a general type of cap which may be used in carrying out this invention, and the specific cap shown is that disclosed in the patent to Ramsey Patent 1,327,963, January 13, 1920. This cap, or a cap of this type either a friction seal or .a hermetic seal, is adapted to set upon the container B, which is a packers jar provided on its upper A zone, 6 against which the inner portions of the concave corrugations are adapted to set.

The sealing zone 6 is of slightly larger diameter than the minimum diameter between the inner portions of diametrically opposed corrugations on the cap illustrated so, that when the cap is forced over the sealing zone the skirt vof the cap is slightlystre'tched and thereby forms a very secure friction seal between the cap and the container, which seal manipulation. The wireedge 5 of the cap tance is accentuated by the undercut groove 7 which is 'ust below the sealing zone 6.

An annu wardly and is formed intoan annular bead 9 is spaced a sufiicient distance from the end of the container to always provide a space 10 between the wire edge 5 of the cap and the shelf'8. This 'space facilitates the inw 1 zone 12 is of a length which sertion of some implement such as a coin 11 into the space, which coin may be twisted between the shelf Sand the edge 5 to force the cap from sealing zone- 6, thereby opening the package.

Figure 3 illustrates a slight modification of the present invention in which the sealing is shorter-than the distance from the top of the cap to the 'crown'of thearch formed by the corrugations in the concave-bead.

This causes the resilient portion of theportion with a sealing is too tight to bebroken by ordinary manual v distance away from ar shelf 8 which extends out-- bead to interlock under and beneath the sealingzone and thereby provides a very tight s'ecure friction seal.'

It, will. be observed that the bead 9 extends outwardly substantially equal to or slightly beyond the wire edge, so that if several packages of this type are set side by side,

the heads 9 will contact and prevent the ment spaced from the mouth thereof, a substantially cylindrical sealing zone adjacent the mouth of the container, and an annular recess between the abutment and the sealing zone; in combination wit-h a cap comprising a skirt having an annular inwardly formed concave bead frictio'nallyengaging the cylindrical zone of the container, said annular bead inthe skirt being corrugated transversely to provi'de for expansion, and a wire edge on said skirt spaced from the annular abutmentand from the bottom of the (annuar recess, whereby opened either by pressing the sealing zone of the container against the cap head to flatten and expand the same or by placing.

an instrument underthe wire edge and using the annular abutment as a fulcrum.
